MF RC522 is a high-integration read-write card chip used in 13.56MHz contactless communication. A low-voltage, low-cost, small-sized contactless card reader chip for "three-table" applications is a smart meter. And a better choice for the development of portable handheld devices. The MF RC522 utilizes advanced ulation and deulation concepts and fully integrates all types of passive contactless communication methods and protocols at 13.56 MHz.
Supports 14443A compatible transponder signals. The digital part handles ISO14443A frame and error detection. In addition, it supports the fast CRYPTO1 encryption algorithm and verifies the IC series of products. The MFRC522 supports the IC series of higher speed contactless communication with bidirectional data rates up to 424 kbit/s.
As a new member of the 13.56MHz high-integration read-write card family, the MF RC522 has many similarities with the MF RC500 and MF RC530, as well as many features and differences. It uses SPI e for communication with the host, which helps to reduce wiring, reduce PCB board size and reduce cost.
[Introduction to RFID ule] The MF522-MINI ule uses RC522 chip to design the card reader circuit. The ule works at 13.56MHz frequency and conforms to ISO14443A standard.Suitable for users of advanced applications such as device development and card reader development, and users who need to design/produce RF card terminals.
This ule can be directly loaded into various reader molds. The ule adopts a voltage of 3.3V, and can directly connect with any CPU board of the user through several simple lines of the SPI interface, which can ensure stable and reliable operation of the ule and long reading distance; the ule is easy to use, highly reliable and small in size. Features such as helping customers to easily and quickly apply contactless cards to the system.
